– The Drive – The potential threat to international commerce posed by naval mines remains palpable. This is especially true when it comes to their deployment around known geographical bottlenecks. When those bottlenecks convey a large portion of the world’s daily oil supply, destabilizing any one of them could have massive economic and even life-safety repercussions around the globe. This is why the growing threat of naval mines in the Strait of Mandeb, the narrow body of water that ties the Red Sea to the Gulf of Aden, is so concerning.

More likely however, it is a thinly veiled attempt at brinkmanship to remind the United States of the kind of trouble that Iran can stir up in the Strait of Hormuz. – See more at: http://news.usni.org/2015/05/11/analysis-irans-latest-round-of-maritime-brinksmanship#sthash.Ladh4PjJ.dpuf
